Controller, vehicle body behavior control system, motorcycle, and control method

A vehicle body behavior control system (10) for a motorcycle (100), the vehicle body behavior control system (10) comprising:

• a peripheral environment detector (41) that detects peripheral environment of the motorcycle (100);
• and
• a controller (60) that controls vehicle body behavior of the motorcycle (100),
• the vehicle body behavior control system further comprising:
• an external force detector (42) that detects an external force acting on a seat (1a, 1b) of the motorcycle (100), wherein
• the controller (60) includes:
• an acquisition section (61) that acquires trigger information generated in accordance with output of the peripheral environment detector (41);
• and
• an execution section (62) that initiates a control mode making the motorcycle (100) execute an automatic brake operation in accordance with the trigger information acquired by the acquisition section (61) and makes the motorcycle (100) generate a braking force,
• the acquisition section (61) further acquires seat load information that is information of a load received by a seat (1a, 1b) of the motorcycle (100) on the basis of a detection result of the external force detector (42), and
• the execution section (62) changes the automatic brake operation, which is executed in the control mode, in accordance with the seat load information acquired by the acquisition section (61).

A control method that controls vehicle body behavior of a motorcycle (100), the control method comprising:

• an acquisition step (S101, S103, S201, S203) of acquiring trigger information that is generated in accordance with peripheral environment of the motorcycle (100);
• and
• an execution step (S102, S104 to S106, S202, S204 to S206) of initiating a control mode that makes the motorcycle (100) execute an automatic brake operation in accordance with the trigger information acquired in the acquisition step (S101, S103, S201, S203) and making the motorcycle (100) generate a braking force, wherein
• in the acquisition step (S101, S103, S201, S203), seat load information that is information of a load received by a seat (1a, 1b) of the motorcycle (100) is further acquired, and
• in the execution step (S102, S104 to S106, S202, S204 to S206), the automatic brake operation, which is executed in the control mode, is changed in accordance with the seat load information acquired in the acquisition step (S101, S103, S201, S203).
